The TeraFlex Elite LCG Long Arm Upgrade Kit is designed as an upgrade to a current suspension system. You get the same advantage and benefits of a long arm system without all of the cost from purchasing parts that you already own and have installed. The Long Arm Upgrade Kit comes with all frame brackets, upper and lower long flexarms, and necessary hardware. Trackbar brackets, and adjustable trackbars are not included, but can be ordered separately.
